As a recent ex-smoker, I can tell you all about giving up but for me it was probably easier than for others because I was not psychologically addicted, just physically. A combination of Zyban and patches and there were NO withdrawal symptoms, it was like someone had switched off an urge in my head almost overnight. I now realise that although I wasn\'t aware of it, my brain was always thinking about the next cig, even though i didn\'t feel like one. I hated the fact that I smoked, those that knew me said I didn\'t look like a smoker and I hated the smell, cough etc - best thing I have ever done, to take control of your life back. Anyway, as far as pheros are concerned, yes I think smoking interferes. My ex- g/f used to say that she could smell nicotine on my skin, its almost as if the skin was secreting it, so chances are it would interfere IMHO. Sympathy for those that do smoke and want to give up, its hard, but boy is it worth it..........
